Reactive transport modeling is a process-based approach that accounts for advection,
diffusion, dispersion and a multitude of biogeochemical reactions. The occurrence of these …

Geological carbon sequestration is one of the key effective technologies proposed to reduce
the atmospheric CO 2, which is essential to achieve the net zero-emission target. Injection of …

We use a pore-scale dissolution model to simulate the dissolution of calcite by HCl in two
different systems and compare with experiment. The model couples flow and transport with …

Polymer-based (gelled or in-situ gelled) and emulsified acids have been used for matrix
acidization of carbonate reservoirs for several years. Gelled and emulsified acids are …

Abstract Effects of heterogeneity of mineral distribution and reaction rate on the rock
dissolution process are investigated using a pore-scale reactive transport model based on …

One of the potential risks associated with subsurface storage of CO 2 is the seepage of CO 2
through existing faults and fractures. There have been a number of studies devoted to this …

In this study we performed three categories of steady-and unsteady-state core-flooding
experiments to investigate capillary trapping, relative permeability, and capillary pressure, in …

We present a new model, named poreReact, to simulate multispecies reactive transport on
pore space images. We solve the Navier–Stokes equations and the advection-diffusion …

Acidic fluid flow in geologic formations leads to mineral dissolution and, under certain
circumstances, to localized dissolution forming a dendritic pattern, known as wormhole …

Fractures are the main flow path in rocks with very low permeability, and their hydrodynamic
properties might change due to interaction with the pore fluid or injected fluid. Existence of …
